DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 355,080, dated December28, "1886.

-Se1lalN0. 215,363. (No model.)

To all whom, it may concern:

Be it known that we, WILLIAM A. HINKLE and FRANKLIN O. JEFFERY, both ofGalveston, in the county of Galveston and State of Texas, haveinvented anew and Improved Door-Check, of which the following is a'specification,reference being had to the annexed drawings, forming a part thereof, inwhich Figure l is a perspective view showing the application of ourimproved door-check. Fig.

. 2 is a longitudinal section showing the door partly open, and Fig. 3is a longitudinal section showing the door fully opened and held inposition by the door-check.

Similar letters of reference indicate corresponding parts in all theviews.

The object of our invention is to provide a simple and efficient deviceforarresting the motion of a door while being opened and for fasteningit in an open position.-

Our invention consists in a slotted plate provided at one end with abuifer for arresting the door, and having in the walls of thelongitudinal slot series of diagonal slots, in combinat-ion with acounterweighted latch provided with trunnions received in the diagonalslots, all as hereinafter more fully described.

The base-plate A is provided with a longitudinal slot, B, extendingthroughout the greater portion of its length, and has,at one end an arm,0, projecting at right angles with the plate, with a chamber, a, in itsvertical face for receiving the hemispherical elastic buffer D. Inoppositewalls of the slot B of 'the frame A are formed series ofdiagonal slots 12, inclined away from the buffer D, and to the slot B isfitted a latch, E, having on opposite edges thereof, near itsmid-length, trunnions c, which may be placed in different pairs ofdiagonal slots 12, according to the thickness of the door in connectionwith which the check is to be used. The end of the latch E nearest thebuffer D is apertured to reduce its weight,

while the opposite end ,is made solid and of sufficient weight tooverbalance the apertured end, so that normally the apertured end of thelatch projects above the upper surface of the plate A and into the pathof the door F, in connection with which the stop is used.,

The door-stop is secured to the floor with the buffer D at thepointwhere itis desired to arrest the door when opened, and thetrunnions of. the latch E are placed in a pair of the slots 1), so as toleave a space between the end of the latch and the buffer B about equalto the thickness of the'door. When the door is opened, it glides overthe latch E, depressing its lighter end and raising its weighted end,

1 .and when the door has passed the latch the lighter end of the latchrises in front of the edge of the door, as shown in Figs. 1 and 3, andholds the door in its open position. When it is desiredv to close thedoor, the latch E is depressed by the foot.

The latch is operated by gravity and re-' quires no springs. It istherefore inexpensive in its manufacture, and not liable to derangement.As the check is secured to the floor instead of the baseboard, as isusual, it may be employed for holding the door open at any de: siredpoint.

Having thus fully described our invention, we claim as new and desire tosecure by Let ters Patent- The combination, with the plate A, providedwith the longitudinal slot B, the oblique slots 6, and the arm 0, of thecounterweighted latch E, provided with trunnions 0, adapted to be.

received in the diagonal slots b, substantiall y as described.
